The regugee crisis of today, one could argue, is a result of supply issues caused by climate change... and things haven't even really started to get bad yet. As things get worse, the people who are impacted will resort to more extreme measures.

Even if we turn this planet into Mars, we can figure out how to live on it... humans are amazing adaptable. The issue is can we scale that up to 10 billion people? I imagine resource wars are the biggest threat from climate change.
